As far as Reisaru goes, I don't have any real structured plot in mind, I just love the pairing to death and want to write as much of it as possible! I do have an AU I kind of love, though, where Saruhiko is a girl who was raised by Kisa instead of Niki, and is a very different kind of fucked up as a result. I'd really like to play that.
My OC is a Blue Clansman, and the main appeal of playing her opposite Saruhiko is that she's kind of aggressively the Mom Friend and fusses over Saruhiko, in particular, because someone needs to. The main idea here is "goddammit Fushimi-san if you won't take care of yourself I guess I'll just have to do it for you." and maybe frustration fucking, because why not.TWEWY:
again, no real plot, I just really like Kirkoma. If you prefer to have a storyline in mind I'm more than willing to brainstorm with you and come up with something, though - that applies in general, not just for this pairing!
As for Josh/Neku: When Joshua was putting Neku back together after shooting him the second time, he accidently left just a little bit of himself behind. That tiny bit of immense power is way too much for Neku to handle in the Realground, and when it starts to negatively affect his life he tracks Joshua down to make him fix it. The problem is that Josh can'tfix it in the RG - his power is too limited - and Neku's really not going to like the only way to get him back into the UG... (Death. The answer's death.) I totally stole this from a Neku-mun I played with once, but it's just such a cool idea...
Seimei and Nisei's relationship is so horribly fascinating and I want to play with it! ("This relationship is interesting and I want to play with it" is kind of a common theme, you might have noticed.) I'd especially love to explore Seimei's reaction to Nisei's attraction to him. Seimei doesn't seem like the kind of person to gracefully turn down someone with a crush.
Dragon Age: Inquisition:
The thing about Effie Treveylan is that she's a shining example of a Circle success story? She's terrified of her magic, of possession, of becoming an apostate - well, more of an apostate than she already is - because she really fell for the idea that all apostates are evil blood mages. I'd love to play her against another mage who realizes why she freaks out so badly after battles and tries to help her overcome the Circle brainwashing. I think Solas is the best suited for successfully helping her, but it would be interesting to see Vivienne and Dorian's reactions to this scenario too. And things would obviously go very differently with Cullen, but, again, I think that would be really interesting. This probably wouldn't be sexual at any point.
As for Bull, well - sometimes you just want fluffy BDSM smut.
No serious plot ideas there - though Bull reacting to and trying to help with Effie's sheer terror of magic could be another interesting take on that plot, especially with his own less than positive attitude towards magic.Persona 3:
I am quite possibly the only one who ships this, but I wrote an AU fic where Chidori falls for Mitsuru instead of Junpei, and the idea hasn't left me alone since. I've also spent way too much time thinking about an AU where Chidori realizes Takaya is an absolute piece of shit and joins SEES instead. And because Takaya is such a piece of shit, Takaya/Chidori is another one of those "super fascinating, want to play" pairings for me. Jin/Chidori's great too. I just really like Chidori, okay.Pokemon
: I have a lot of... probably over-elaborate headcanon regarding Giovanni and Domino's relationship and why she's, from what we can tell from her limited screentime, so close to him. The basic idea is that he met her when she was very young, thought she had a lot of potential, and handpicked her to receive special training. Along the way he conditioned her to feel safe in his presence, even though she's constantly on guard everywhere else - and even if he's not treating her in a way that should make her feel safe.
For Attila and Hun - I think the only way to get Hun to break down would be to do something to Attila. So let's do something horrible to Attila! Hurt/comfort between the two of them or conflict between Hun and Attila's tormentors would both be great.
My OCs are also Team Rocket - surprise, surprise - and I'd love either a police capture and interrogation thing, or a buying-promotions-with-sex thing with a higher ranking member of Team Rocket.
